UnreachableBrowserException - 在 OrangePiOne (Ubuntu 18.04.2) 上使用带有 java 的 PhantomJS 时

Question

我想用我的小型 Java 程序使用PhantomJS 在网站上填写一个 html 表单。它在我的 Win 10 机器上进行了测试，并且运行良好。我也想在我的OrangePiOne (Armbian 5.85 and Ubuntu 18.04.2) 上运行它。每次我运行程序时，都会出现以下异常：

在以下方法中，我正在设置驱动程序，但在返回语句期间出现异常：

private WebDriver createDriver(String phantomjsExeutableFilePath) {
        Suche.log(":::phantomjs path: " + phantomjsExeutableFilePath);
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setJavascriptEnabled(true);
        capabilities.setCapability(PHANTOMJS_EXECUTABLE_PATH_PROPERTY, phantomjsExeutableFilePath);
        return new PhantomJSDriver(capabilities); // Exception is thrown here
}

我已经从官方网站下载了PhantomJS 库和chmod'ed 它。 可能是OrangePiOne的错还是我遗漏了什么？

当我为 rasberry pi 使用 phantomjs 构建而不是来自官方网站的那个时，它起作用了。 此问题已通过来自https://github.com/fg2it/phantomjs-on-raspberry 的phantomjs-on-rasberrypi 解决。
